+Subject: [PATCH] Fix test_snippets_completion to not depend on typeshed
+ overload ordering
+
+jedi 0.20.0 bundles a newer typeshed that adds a no-arg overload for
+defaultdict.__init__ as the first overload, causing format_snippet to
+hit the zero-params branch and produce "defaultdict()" instead of
+"defaultdict($0)". Replace defaultdict with a locally-defined function
+to make the test stable across typeshed updates.
